1.1 Structure and Crystallographic Feature of Al Two O THREE

(Alumina Ceramic Balls， Alumina Ceramic Balls)

Alumina ceramic spheres are round parts fabricated from light weight aluminum oxide (Al two O SIX), a totally oxidized, polycrystalline ceramic that exhibits phenomenal solidity, chemical inertness, and thermal stability.

The key crystalline stage in high-performance alumina spheres is α-alumina, which adopts a corundum-type hexagonal close-packed framework where aluminum ions inhabit two-thirds of the octahedral interstices within an oxygen anion latticework, providing high latticework power and resistance to phase change.

Industrial-grade alumina rounds commonly consist of 85% to 99.9% Al ₂ O TWO, with pureness directly affecting mechanical toughness, wear resistance, and deterioration performance.

High-purity grades (≥ 95% Al ₂ O FIVE) are sintered to near-theoretical density (> 99%) using advanced techniques such as pressureless sintering or warm isostatic pushing, lessening porosity and intergranular flaws that can act as anxiety concentrators.

The resulting microstructure consists of fine, equiaxed grains uniformly distributed throughout the quantity, with grain sizes usually varying from 1 to 5 micrometers, enhanced to stabilize toughness and solidity.
